Immediate active range of motion after modified 2-incision repair in acute distal biceps tendon rupture.
BACKGROUND
Different rehabilitation protocols have been used after repair of distal biceps ruptures.


OBJECTIVE
This study investigates the safety of immediate active range of motion protocol after modified 2-incision distal biceps tendon repair in acute ruptures.


METHODS
Case series; Level of evidence, 4.


METHODS
Twenty-one patients with a minimum follow-up of 2 years were participants in this study. After repair, the upper extremities were placed in a sling for 1 to 2 days and then immediate active range of motion was started. For the first 6 weeks, the elbow was allowed activities of daily living as tolerated by the patient with a 1-lb weight-lifting restriction. Elbow range of motion, isometric and dynamic flexion, and supination strengths were recorded and Disabilities of the Arm, Shoulder and Hand (DASH) scores were obtained.


RESULTS
Mean follow-up extension was 0 degrees and mean follow-up flexion was 141 degrees on the operated side, with supination of 74 degrees and pronation of 75 degrees. The mean DASH score for 21 patients was 3.6 +/- 3.6 (range, 0-11.4). The mean follow-up isometric flexion strength was found to be 5% (P = .411), and the power (dynamic strength) of flexion was 12% greater on the operated side (P = .046). However, follow-up isometric supination strength was 9% less on the involved side than on the noninvolved side (P = .030), and the power of supination was 11% less on the operated side (P = .007). There were no tendon reruptures at follow-up, determined by physical examination.


CONCLUSIONS
A modified 2-incision distal biceps repair allows a safe immediate active range of motion protocol with early return of nearly full range of motion and strength, without any clinically significant disability.
